Trouble with command line tools

[M A]

This led to a solution! I didn't delete
/Library/Developer/PrivateFrameworks/CoreDevice.framework, but in the
reddit thread someone mentioned executing "sudo xcodebuild
-runFirstLaunch". This resulted in the downloading and installing of some
things and now "make" and other build commands work fine. Macport builds
are again proceeding without problem. Even Xcode will successfully launch.
I don't know why so many things built just fine, and then suddenly stopped,
but at least they're working now. Thanks for the suggestion!
